KMPROVEMENT IN BOATS FOR TRANSPORTING NIGHT-SOIL.

Specification forming part of Letters Patent No. 129,982, dated July 30,1872,

To all whom it may concern:

Be it known that I, JOHN PATERSON, of Hoboken, in the county of Hudsonand State of New Jersey, have invented a new and useful Improvement inNight- Soil Boats; and I do hereby declare the following to be afull,clear, and exact description thereof, which will enable those skilled inthe art to make and use the same, reference being had to theaccompanying drawing forming part of this specification, in which draw-1ng-- Figure 1 represents a longitudinal vertical section of myinvention. Fig. 2 is a transverse section of the same in the plane a: m,Fig. 3. Fig. 3 is a horizontal section of the same.

Similar letters indicate corresponding parts.

This invention consists in the arrangement of compartments in the end ofa boat, said compartments being separated from the central compartmentor compartments by bulkheads, provided with openings, which are situatedat about the middle of the bight of said bulk-heads and protected bystrainers, in combination with pumps, the suction-pipes of which extenddown into the end compartments, while their discharge -pipes lead out inthe open water in such a manner that when the night-soil is dumped intothe central compartment or compartments of the boat the liquid portionthereof, as soon as the same rises up to the openings in the bulkheadsleading into the end compartments, flow over into these compartments,whence the same can be readily removed by the pumps; and by these meansthe boat can be charged with solid matter free from liquid, and thenumber of trips required for removing a certain quantity of night-soilis materially reduced.

In the drawing, the letter A designates a boat, which is provided withcompartments B B at its ends and one or more compartments, 0, in themiddle. The end compartments B B are separated from the centralcompartment or compartments by bulk-heads a a, which are provided with.apertures b b, situated at or about the middle of the height of saidbulk-heads, and protected by screens 0 c, of wire-netting or othersuitable material. The central compartment 0 may be divided in a'seriesof subdivisions by a longitudinal bulk-head, d, and one or moretransverse bulk-heads, e, and the end compartments may also besubdivided by bulk-heads f; and if such subdivisions are made thebulk-heads 01 cf are provided with apertures g, near their bottoms. Theobject of these subdivisions is to strengthen the boat and to preventthe contents of the same from surging. In the deck of the boat arehatchways D, which lead into the central compartment, and through whichthe night-soil is dumped into the boat. As the material which is dumpedinto the central compartment rises therein the liquid mixed therewithascends to the top and flows over through the apertures b I) into theend compartments, which are provided with pumps E E, the discharge-pipesh h of which extend out through the sides of the boat (see Fig. 2) anddown beneath the water-line.

.By means of these pumps the liquid can easily be removed from the endcompartments, and, as the same while being pumped out discharges beneaththe water-line, all unpleasant odor is avoided. The principal object ofmy invention, however, is to remove from the boat all the liquid partswhich cannot be employed usefully in the manufacture of poudrette, andto retain only the solid parts; and by removing the liquid parts whilethe boat is being loaded I am enabled to carry an increased percentageof solid matter, and the number of trips required to remove a certainquantity of night-soil can be reduced.

It must be remarked that one or more com partments for receiving theliquid might be arranged in the middle of the boat but this arrangementwould be substantially the same as that shown in my drawing.

What I claim as new, and desire to secure by Letters Patent, is-

The arrangement, in a boat, of one or more compartments, provided withpumps, and which communicate with the remaining compartment orcompartments by overflow open- This specification signed by me this 7thday ings, said openings being protected by strainof June, 1.872.
